Unlike the complainers you mention, I was warned not to expect much in the way of earnings or views until after months of networking and posting, so I'm not even slightly disgruntled. I find the site fascinating and enjoyable. Connecting with people on it is a thrill. It will not surprise me when site-related cryptocoins gain in value.

However, you just said something that took me aback. "I check the poster's wallet and most of the time they have 40 or 50 Steem Power, mostly delegated when they opened the account - i.e. they have invested not one single $ of their own money"

Hmm. I def had to invest some of my own USD (via ETH) before I lifted my Steem Power past 40. Now, don't get me wrong. I'm fine with making that investment. But I wonder: If I had complained, and if one of the complaints you saw had been mine, would you also be presuming about me that I had not invested anything?
